3500/46M Hydro Monitor
The Bently Nevada™ 3500/46M Hydro Monitor is a four
channel instrument that accepts input from proximity,
seismic, dynamic pressure and air gap sensors. The monitor
conditions the signal to provide vibration, position and both
static and dynamic pressure measurements. It then
compares the conditioned signals with user-programmable
alarms. Hydro Radial Vibration channels combine the shaft
gap movement with the NX amplitude to provide a
measurement to alarm on shear-pin failure.
Using the 3500 Rack Configuration Software, you can
configure the 3500/46M Hydro Monitor to perform the
following functions:
l Hydro Radial Vibration
l Hydro Air Gap
l Hydro Velocity
l Hydro Acceleration
l Hydro Thrust
l Multimode Hydro RV
l Multimode Air Gap
l Multimode Hydro Velocity
l Multimode Thrust
l Multimode Acceleration
l Multimode Hydro Dynamic Pressure
l Hydro Stator End Winding (SEW)
